HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 198, 317, 913 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 198, 317, 913 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 198, 317, 913 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 198, 317, 913 is 1.
HCF(198, 317, 913) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 198, 317, 913 is 1.
Step 1: Since 317 > 198, we apply the division lemma to 317 and 198, to get
317 = 198 x 1 + 119
Step 2: Since the reminder 198 ≠ 0, we apply division lemma to 119 and 198, to get
198 = 119 x 1 + 79
Step 3: We consider the new divisor 119 and the new remainder 79, and apply the division lemma to get
119 = 79 x 1 + 40
We consider the new divisor 79 and the new remainder 40,and apply the division lemma to get
79 = 40 x 1 + 39
We consider the new divisor 40 and the new remainder 39,and apply the division lemma to get
40 = 39 x 1 + 1
We consider the new divisor 39 and the new remainder 1,and apply the division lemma to get
39 = 1 x 39 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 198 and 317 is 1
Notice that 1 = HCF(39,1) = HCF(40,39) = HCF(79,40) = HCF(119,79) = HCF(198,119) = HCF(317,198) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 913 > 1, we apply the division lemma to 913 and 1, to get
913 = 1 x 913 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 913 is 1
Notice that 1 = HCF(913,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
